String Data Types in MySQL and PostgreSQL

Aisha Bukar compares two products:

A very common task in creating a database is to store string data. For example, words, paragraph(s) or even documents. String data types allow you to do just that and store and represent text. They handle everything from simple names and addresses to complex data.

A string is simply a sequence of characters. These characters can be letters, numbers, symbols, or even spaces. For example, “Simple Talk”, “MySQL and PostgreSQL”, “1234” are all strings. Think of each character as a building block. A string is made up of these blocks, arranged in a specific order.

As always, when dealing with different data platform technologies, the small differences are big.
